Unable to free up space on xs max

I have a 64 gb iphone XS Max with a public beta of IOS 12.3 loaded. I dont know what happened but up until 3 days ago, I had 47 gb available on my iphone. The other day I was trying to upload a few pics from my laptop to my phone and I installed the Windows 10 application icloud which I have used in the past. Long story short, I now have 39.21gb which is by no means out of room but no matter how many videos,photos,apps I remove or how many times I restart my phone, that number never reduces and I dont know why. Anybody have this issue? Also I noticed that even though my app updates are set to automatically update, they do not. I have also used the feedback assistant but wanted to post this in the meantime.

Thanks

John
